Title: System for positioning angle of arrival for tracking objects
IPC: H04W4/029
Filed: 2021-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for determining user apparatus (UE) locations within a wireless network range using a reference signal of a wireless network. 
     SOLUTION: The disclosed system and method utilize a plurality of in-phase and quadrature (I/Q) samples generated from signals provided by receive channels associated with two or more antennas of a wireless system. Based on received reference signal parameters, a reference signal within a range of the signals from each receive channel among the receive channels is identified. Based on the identified reference signal from each receive channel, an angle of arrival between a baseline of the two or more antennas and incident energy from the UE to the two or more antennas is determined. The angle of arrival is then used to calculate a location of the UE. The angle of arrival may be a horizontal angle of arrival and/or a vertical angle of arrival.
